Product Description

Huitai 40# Garnet Abrasive Sand Sandblasting Material
 
 
1. Product Introduction
 
Garnet sand is a mineral material made from garnet crystal powder. Its main component is silicon dioxide (SiO2) and a small amount of metal oxide impurities. Garnet sand has high hardness, high density and excellent corrosion resistance, so it is widely used in abrasives, cutting tools, ceramics and other fields.

2. Characteristics
 
①The texture of garnet sand is hard, with a Mohs hardness of more than 7.1, which is higher than that of commonly used quartz sand, sea sand, river sand and other sandblasting materials, and has a long service life.
 
②Because garnet is a crystal of an isometric system and has no cleavage, which it is easy to form approximate cube particles with edges and angles after making it into sandblasting, and the effect of sandblasting and rust removal is better. It can not only completely remove the rust, oxide skin, coating and its pollutants on the metal surface, but also because of its high hardness, it can produce an ideal angular rough surface on the cleaned metal surface, increasing the surface area of the metal, improving the adhesion of the interface, and making the binding force of corrosion-resistant protective coating and the metal surface significant. So it can enhance to improve the bonding performance of the coating and the metal surface.
 
③The density of garnet sand is larger, usually about 4g/cm³, strong impact force, which can better clean the metal surface.
 
④High strength. Treating the metal surface,garnet sand is not easy to break. Even after it is broken, it will produce new angular, almost cubic particles, so that it can be used repeatedly, usually up to 20 times. It is 20 times of siliceous sand (sea sand or river sand) and more than 2 times of quartz sand (artificial), and its relative cost is low once used.
 
3. Application
 
Surface pretreatment of metal and steel structures, etc
This is one of the more widely used fields of garnet sandblasting. It can be used for electroplating, spray painting, spraying and other all covered before sandblasting processing, which can achieve a clean surface, and improve the roughness of the substrate surface, enhance the adhesion of the coating, extend the life of the coating, especially for ships and other large equipment.
 
Cutting tools: It can be used to make cutting tools such as HSS blades and saw blades to improve their service life and cutting efficiency.
 
Glass manufacturing: As one of the main raw materials of glass, it is used to make glass with high hardness and good transparency.
